Customer testimonials

For more than 10 years, we have been providing quality professional service in dozens of countries.
Faithful to FLEXINA since always, a real pleasure and a very efficient tool on a daily basis. We had tried many different invoicing software and none of them offered such latitude in settings and customizations. You can also count on an extremely efficient and responsive technical service, which makes each handling very smooth. A must have for all freelancers and companies who want an all-in-one tool without any hassle. Thanks to the whole team!

I have been using Flexina for 13 years, it is an excellent invoicing software which is complete (quote, order form, delivery note, invoice, etc.). It is easy to use, with its application and the Cloud, it allows access to documents from anywhere and with any device. Regular updates whose payment with QR code is very practical. I highly recommend this invoicing solution.

I take this digital pen to say that I find that Flexina is a company that fights hard to satisfy us, what's more, with an excellent team behind, available, at the listen, and above all reactive! Nothing to complain about, I use Flexina every day, even on weekends, and it works great! 100% recommended.
